COMBINED CHURN' AND BUTTER-WORKER;

" Application filed March 6, 1914. Serial No. 822,856.

To all whom/it may concern:

Be it known that I, FRANK LA BARE, of Owatonna, Steele county, Minnesota, have invented certain new and useful Improvements in Combined Churns and Butter- Workers, of which the following is a specification.

This invention relates to improvements in combined churns and butter workers, and

particularly to that type of machine in which a pair of butter working rolls is arranged within a revoluble drum and are held, during the butter working operation, in a stationary position, while each of said rolls is rotated inwardly toward the other upon its own axis and the butter which is carried up by the wall of the drum and flights thereon is dropped onto the rolls and is. passed between them, this operation being repeated as often as necessary until the butter is completely worked.

My present invention relates particularly to improvements in the combined churn and butter worker describedand claimed in Letters Patent of the United States No. 866,038, issued to me September 17 1907. a

The object of my present invention-is to provide means for causing the butter, after it has been worked, to'pile up in the vicinity of the door opening, so that it can be easily removed from the combined churn and butter worker. I

The invention consists generally in. the constructions and combinations hereinafter described and particularly pointed out in the claims. p

In the accompanyingdrawings forming part of this specification Figure 1 is a transverse vertical section of a combinedchurn and butter worker embodying my invention. Fig. 2 is a longitudinal horizontal section of the same. Fig. 3 is a side elevation of a portion of the frame and the forward end of a churn with my improvement applied thereto. Fig. 4; is an end elevation of the mechanism shown in "Fig. -3 with the driving pulley omitted. Figs. 5, 6, 7 and 8 are details.

flights of ordinary width and construc tion, but any desired number. thereof may be employed. The churn drum issupported in a suitable frame 1, ofany suitable form and construction. It may be substan tlally that shown in my former patent above referred to. It is provided with suitable means, whereby when the machine is operated for churning the sectional heads 14:, the cross heads 11 andthe rollslO maybe all locked ;to androtated with the drum. I. prefer in this-constructionto employ also the rectangular bars 31 mounted upon gudgeons, capable of rotating freely upon their axes. These bars are usually designated .roller shelvesv and they are mounted loosely in the cross heads 11, and the pur: pose is to'permit saidbars to turn upon their axes in case any butter lodges upon one corner or edge thereof, thereby causing said butter to fall off. from these bars,- either by falling back into the churn or falling forward into the butter workingrolls.

Butter working rolls 10 are mounted in the cross heads'll and their gudgeons 12 extend through the sectional head 14:, at one end of the drum and they are provided with suitable means by which saidrolls may be driven, preferably as set forth in my Patent No. 866,038, hereinbefore referred to.

, The ends of the drum are preferably sup machine by suitable spiders 7-provided with hollow gudgeons Swthat arev rotatably arranged in bearings in the frame of the ma- .chine. The forward end of the drum is preferably provided with a ring gear 9 eng'aged by a pinion 13 on'a dog 13, and this pinion may be driven from the driving pulley 17 at either a fast or a, slow speed, thereby permitting the churn drum to be revolved rapidly during the churning operation and to be revolved slowly during the butter working operation. The driving pulley 17 is loosely mounted upon the shaft 13. The pulley may be connected with said shaft 13 by a suitable clutch device; -A sleeve 20 has secured to it asuitable pinion 21. v The pinion 13 may be driven directly from the sleeve 20 bymeans of the sliding sleeve'23 splined to the shaft 13' or indirectly through the back gears 21, 24:, 25 and .26, in a mannerwell understood in this class of machines. A pinion 27 may be caused to V rotate with the gear 24, and this pinion,

through the gears 28 and 29, is arranged to rotate a shaft 32 carrying a pinion 33 that drives the roll gears 34 and 35. A tubular shaft 36 is arranged within the gudgeon 8 of the spider 7 and forms a bearing for the shaft 32, which carries at its forward end the gear 29 and at its rear end the pinion 33 hereinbefore referred to. Mounted upon the forward end of the-gudgeon8 is a sprocket pinion 37 and splined upon the forward end of the tubular shaft 86 is a disk 38 (see Fig 5), having the peripheral 41' upon the, arm 4:2forming 'a part of the frame of "the machine.- A lever 43 is provided for moving said disk '38 longitudi nally upon the tubular shaft36. When the parts are inthe position shown in Fig. 8 the cross hea'ds carrying the rolls, and consequently the rolls, will be held in a stationary position, and preferably with the cross headsllinclined-substantially as shown in Fig. 1 of thedrawings. J VVhenthe device is to be used for churning the. disk 38 is moved in the opposite direction by the lever 43, and the tubular shaft, the disk 38, and the sprocket 37 are all looked tothe gudgeon' 8 and rotate with the drum. A chain belt 45 passes" around the pinion 37 and drives a shaft 46 thatruns lengthwise of themachine near the botto'm'of the frame (see Fig. 4:). This sha'fthas a suitable connection (not shown) with a tubular shaft carrying the cross head at the opposite end of the machine- The churn body is provided with a suit able dooriopening 15am one wall thereof and this opening is provided'with a suitable door 16. When the door is closed the churn body is" rendered cream tight, and when it is openedthe' butter "may be removed through the door opening; I

Y The cross heads 11, the roller shelves 31 .mounted loosely'therein; andthe rolls 10 having their 1 gudgeons' passing through the said crossheads "and' through the sectional headsll, are capable of being turned and locked by the means described with the plane of the rolls at any desired angle. In ordinary practice during the butter working operation the rolls willbe in substantially the position shown in Fig. 1 of the'drawing, with the plane thereof inclined toward. the

"door opening and when the' butterworking 'tially as described.

flight 18 substantially fills the space between the cross heads and roller shelves and the inner wall of the drum, thereby forming a jacket or hopper to hold the butter in position to be conveniently removed through the door opening.

When the cross'heads 11 are in the position shown in the drawing there is an inclined and practically level surface consisting of the tops of the roller shelves 21, the rolls 10 and the shelf 18. The'butter may all be brought into that section of the drum which contains the door 16, and then by having the broad shelf 18 in the position shown in. the drawing with the cross head 11 set in the position also shown in the drawing, a large hopper is formed immediately by the door-opening in whichall of the butter can be gathered in position to be quickly removed through said door'opening.

I also find that by locking the rolls and drumtogether during the churning'operationwith the broad flight parallel with the supporting said rolls parallel with "each other, means for rotating the drum 'while the crossrheads remain in a stationary position-with thedrum rotating about said cross heads and the rolls supported thereby, means for rotating the rolls upon their own axes, means for locking the said supporting cross heads in 'astationary position with the plane of the rolls at any desired angle, flights upon the interior of said drum, the width of the flight which is below the door opening being substantially equal to the dis tance between the ends of the cross'heads and the periphery of the drum, whereby when said cross heads are locked, said last named flight may by a revolution of the and the wall ofthedrum and form a pocket or hopper on which the butter will rest in convenient position to be removed from the drum through the door opening, substan- 2.'In' a combined churn and butter worker, the combination, with a revoluble drum, having a door opening in the peripheral wall thereof, of a pair of butter working rolls arranged in said drum, cross heads supporting said. rolls below the axes of the drum and parallel with each other, means for rotating the drum while the cross heads remain in a stationary position with the drum rotating about said cross heads and the rolls supported thereby, means for rotating the rolls upon their own axes, means for locking the said supporting cross heads in a stationary position with the plane of the rolls at any desired angle, flights upon the interior of said drum, the width of the flight which is below the door opening being substantially equal to the distance between the ends of the cross heads and the periphery of the drum, whereby when said cross heads are locked, the last named flight may by a revolution of the drum be brought into a position to substantially fill the space between the cross heads and the wall of the drum, and forma pocket or hopper on which the butter will rest in a convenient position to be removed through the door r FRANK LA BARE.
